IDT23S08

3.3V ZERO DELAY CLOCK MULTIPLIER

ZERO DELAY AND SKEW CONTROL

To close the feedback loop of the IDT23S08, the FBK pin can be driven from any of the eight available output pins. The output driving the FBK pin

will be driving a total load of 7pF plus any additional load that it drives. The relative loading of this output (with respect to the remaining outputs) can adjust

the input-output delay.

For applications requiring zero input-output delay, all outputs including the one providing feedback should be equally loaded. Ensure the outputs are

loaded equally, for zero output-output skew.
